Overview

The AdminTuning E85 conversion kit is designed for Nissan 350Z, 370Z, and Infiniti G35, G37, and 3.7L Q50 models. This kit features AdminTuning spec 650cc/min fuel injectors and an AEM 340LPH fuel pump, along with a CJM installation kit for straightforward installation.

The injectors are plug-and-play, fitting factory wiring harnesses and fuel rails without modification. This kit is specifically for naturally aspirated Nissan and Infiniti vehicles intended to run both 91/93 octane gasoline and E85 fuel, requiring tuning solutions. The injectors are characterized to provide excellent startup, idle, and driving performance while offering the necessary flow for E85.

Switching fuel types without a flex fuel sensor requires running the tank near empty. The product can result in noticeable horsepower increases when transitioning from 93 octane to E85.

The Admin Tuning E85 Conversion Kit provides a comprehensive fuel system upgrade for naturally aspirated Nissan 350Z, 370Z, and Infiniti G35, G37 vehicles, enabling the use of both standard gasoline (91/93 octane) and E85 fuel when paired with compatible tuning solutions. Included in the kit are high-flow AdminTuning spec 650cc/min fuel injectors, which are designed to be plug-and-play with the factory wiring harness and install directly into the OEM fuel rails without requiring any modifications. Complementing the injectors is a robust AEM 340LPH fuel pump, ensuring sufficient fuel delivery to support the demands of E85 fuel. A CJM installation kit is also provided for a hassle-free and reliable setup. The injectors have been meticulously characterized to function similarly to stock injectors, ensuring excellent startup, idle, and overall driving characteristics. This careful calibration ensures that while the system can handle the increased flow needed for E85, it doesn't compromise daily drivability on pump gas. When combined with Admin Tuning's tuning solutions, users can expect significant performance gains, with documented increases of up to 14whp observed when switching from 93 octane to E85. For optimal results and to fully leverage the capabilities of this E85 conversion kit, it is recommended to install the product close to your scheduled tuning date. Admin Tuning advises driving conservatively until the tune is completed. Unless a flex fuel sensor is purchased and installed, drivers will need to manage fuel type changes on a near-empty tank to avoid mixing fuels.
